How many fluid ounces do you drink?

I figure I drink around that much coffee in a day. I have a coffee mug that fits about 12-14 ounces of coffee in it, and I normally drink two of those cups in a day. If I get up particularly early and have a good load of work to do, I might get a third one at some point.

In my first few years of university I drank about twice that amount, but nowadays I can hardly sleep if more than one of my coffees is caffeinated. I guess I've learned how to sip it more than chug it.

I also drink about one and a half to two times that amount of water a day.

The thing with this big drink is that I can't imagine it being too practical to carry around. The worst part would be trying to get it into a car's cup-holder. If your going to be setting it down somewhere while your doing something or sharing it with someone, I can see that it might not be such a bad idea.

Jam it back in, in the dark.
